LONG-RANGE PROJECTILE.

Application filed August 10, 1920. Serial No. 402,729.

FETE F. SMITH, citizens of the United States, residing at Herrin, in thecounty of Wil- 5 liamson, State of Illinois, have invented certain newand useful lmprovements in Long-Range Projectiles; and we do herebydeclare the following to be a full, clear, and

exact description of the invention, such as will enable others skilledin the art to which it app Thi impro ertains, to make and use the same:s-invention relates to new and useful vements in projectiles andparticularly to long range projectiles.

One object is to provide a novel and improved device of this characterwhich has means for facilitating the steady flight ot the device throughthe air.

Another object is to provide guiding means for a projectile which'obviates the use of the rifling of the barrel of the gun, together withthe particular manner in which the guiding means are supported on theprojectile.

Other objects and advantages will be apparent from the followingdescription when taken in connection with the accompanying drawing.

ln the drawing Fig made

ure 1 is an elevation of a projectile in accordance with our invention.

Figure 2 is a vertical longitudinal sectional view through theprojectile.

Figure 3 is an enlarged vertical transverse sectional view taken on theline '3-3 of Fig. 2.

Fig

ure 4 is a vertical sectional view taken on the line 4-4. of Figure 2,enlarged.

Figure 5 is a rear elevation of the projectile.

Figure 6 is an enlarged vertical transverse sectional view taken on theline 6--6 of Figure 2.

Referring particularly to the accompanying drawing, 10 represents theelongated hollow body of the projectile, the rear end being of the samediameter as the intermediate portion, while the forward end is taperedto form the nose 11. Extending longitudinally through the body 10, andhaving it forme s ends secured in openings 12 and 13, d respectively inthe nose and butt ends of the body, is a tube 14, and rotatablysuptending shaft 15. Rotatably carried by the forward end of the shaft,and disposed forwardly of the nose of the body, is a screw 16. Similarlymounted on the other end of the shaft, and disposed rearwardly of thebutt end of the body, is a second longer screw, this latter propellerbeing longer so that a more perfect balance of the body, during itsforward flight through the air will be assured, said propeller beingshown at 17.

The forward screw 16 is formed with a hub portion 18 which is receivedin a cup member 19 threadedly engaged in the nose of the body, and whichbears against the circular series of ball bearings 20, disposed in saidcup member. The rear screw 17 is similarlyk provided with a hub portion2l which engages the balls 22 disposed in the cup member 23 in the rearor butt end of the body. Surrounding the cup member 23 are the series ofinternally threaded openings 24C into which are engaged screw plugs 25.Through these openings, when the plugs are removed, the explosive isintroduced into the interior of the body of the projectile. Theprojectile is arranged to be placed in the outer open end of the shell26, in the manner of the ordinary bullet of the common rifle shell, awad 27 being disposed behind the rear screw 17, and in front of thecharge of explosive which is adapted to drive the projectile from theshell. A fuse 28 is disposed through one of the openings 24 and througha groove formed in one of the plugs 25. The inner end of the fuse isdisposed within the mass of explosive within the body of the projectile.

As the projectile proceeds through the air the screws 16 and 17 willrotate at a high rate of speed serving to keep the projectile onL aneven keel while at the same time directing the same on its course. Therear screw 17 being longer than the front one will act in the manner ofthe feather of an arrow to more properly insure the direct flight of theprojectile.

What is claimed is:

A projectile comprising an explosive containing body, a tube disposedlongitudinally through the center of the body, a rotatable In testimonywhereof, we al'lx om.' signasllait dlsposed through the Said tube, a,tures, 1n the presence of two wit-Deseas. conical screw mounted on theforward end of the shaft externally of the body, and a TADAUS LYBURS.Cylindrical Screw mounted on the new end PETE'F.
